4.2 During an active MAC session with WOR activated 302
In this section, we address the recommended logic when the end-device already has a valid 303
MAC session (following a successful join procedure for OTAA end-devices) and currently 304
activates the WOR mechanism. In this case, the following recommendation instructs the end- 305
device when to deactivate the WOR protocol (i.e. disable the relay mode). 306
307
Case JOINED_WOR_ACTIVATED // the end-device has an active MAC session where the 308
WOR protocol is currently activated. 309
Deactivate WOR and proceed to the JOINED_WOR_DEACTIVATED case, in any of the 310
following cases: 311
• If the relay mode is deactivated by the network server through the MAC command 312
EndDeviceConfReq with RelayModeActivation = 0, or 313
• If the success rate of downlink frames received on RX1 or RX2 is greater than 80%. 314
This success rate is evaluated over a sliding window of the last 10 downlink packets, 315
by inspecting the downlink frame counter. If needed, the end-device may trigger the 316
transmission of downlink frames either by using a confirmed-data-uplink frame, or by 317
sending LinkCheckReq. 318
